| Zusammenfassung |
| Bogs, fens, marshes, and swamps are waterlogged ecosystems where organic soils form and
peat accumulates. These are remarkably diverse ecosystems and represent an important
component of the biodiversity found on Earth. Their geochemical function is dominated by
their predominately anoxic condition which has some important consequences. Best known
as reservoirs and reactors for a significant part of our surface freshwater resources, and
impacting their chemical composition in remarkable ways, they also have a significant
influence on the atmosphere, removing CO2 and adding CH4. The contemporary view during
the past centuries was that these were wastelands in need of improving by drainage. Today,
however, in some circles at least, the remaining wetlands are valued ecosystems, and the soils
they contain archives of climate change, human history and atmospheric pollution. |
